Overviewing basics of event processing in Event-Driven Architectures:

• Typical structure of microservice
• Typical types of event transformations, 2 branching scenarios, merging streams
• Repartitioning events and when it can be useful
• Copartitioning events and when it is needed
• Assigning Partitions to a Consumer Instance. Three strategies to do this.
• Recovering from stateless processing instance failures.

These topics are disclosed in the Chapter 5 of the book we are currently studying:
